Cheng Xuelin, the old urchin in the jewelry circle, we have known each other for ten years, in terms of seniority, he is my elder, should not have no rules, but also mixed together, his age and my father are almost the same, my master's mother was his father's graduate student in the early years, no matter from which aspect, I am so late, but I use "my friend Hu Shizhi" tone, Have the gall to call him my friend, a pair of forget-of-age friends. When in Beijing, we talked about jewelry works together, collected chicken feathers together to hold exhibitions, chatted in bars and talked big, and said that we would do something practical for China's jewelry industry. After I left Beijing, they set up the China Jewelry Designers Association, and I worked in Panyu as my jewelry factory, but I still kept in touch with them by phone, and every time I returned to Beijing, Lao Cheng always invited me to his home early to see his new works and enjoy a feast of art jewelry.
